Hello All. Just purchased this 1966 Kennedy half from ebay. The description was Clad Missing Error. I weighed the coin, 9.5 grams. It's much thinner than the other 1966 Halves that I have. What do you think? How can I tell if it's real or not? I'm uploading pics also. If you need more or additional information, please let me know. Thanks.    |

looks good to me as authentic and There would be no reason to make a fake 66 Kennedy I could think of. |

Thanks for the Welcome Guys. Do you know why it would be so thin and only weigh 9.5g instead of 11.5g? Could it be struck on a different planchet? I checked the US Mint site and the weight is not close to anything else.

I found a 1942 New Zealand Penny is 31 millimeters and 9.5 grams but is bronze in color. Looked for others but nothing yet for a wrong planchet. Check your scale and see if a US nickel weighs 5 grams. Maybe your scale is off, maybe it is a thin planchet or it's a wrong planchet but I don't know.
2 grams off is significant I would think.

Thanks. Just weighed 5 different nickels. All of them are at or near 4.98 grams, so it looks like the scale is slightly off. I'm going to take this to the Coin shop tomorrow to verify. I've got another 1976 Half that I also bought from ebay. I think I got scammed on that one. I'll post later...I think I can only handle one "problem" at a time. Lol. |

FYI. I found someone else online that had this same type error, but on a 64 Half. The site was errorcoininformationexchange on yahoo. They were calling it a "rolled to thin" planchet error. Hopefully the Coin shop will tell me tomorrow.

This is a genuine missing clad error. The 80% silver clad layer on the obverse face split off prior to the strike.

Thanks MikeDiamond. So that should account for the 2 gram loss in weight (mine is 9.5g) and the smaller thickness. Any idea what it is worth? It's really hard finding information on these types of errors.

I'm a little confused about these 40% silver halfs.
Was the stock (pre blank punch) already made of the composite.
Logic says yes. The way they were composed seems to be different than say a copper/nickel clad modern coin. I thought
that the composition consisted of an outer layer composed of 80% copper and 20% nickel with a core of 20.9% silver and 79.1% copper. This yielded a net composition of 40% silver.
So only the obverse of this particular coin is missing a layer ? The rev. seems to look add also as far as color
compared to a normal 40% silver half.

Yes, the 40% silver clad planchets are different from their CuNi counterparts in that the core is not pure copper. The outer layers are 80/20 AgCu and the core is 20/80 AgCu, there is no nickel content at all in the 40%ers.

Update. Took the coin to a Coin shop. Owner said he wasn't sure about the type of error, but he weighed it and told me it's 1 Penny weight under what it should be. He did however tell me to hold on to it, but couldn't give me a value.
I'm still curious, especially since 80% of Silver is on the outer layer (as Several people here have stated).
I appreciate all of the input. Thanks.

Now I'm really confused. My math comes out
incorrect as far as silver content if what you stated
about it's composition. 80% Silver out/20% in ? (layers)

All different sorts of info out there on exactly
what these are.

The RedBook will list the correct specs under 1965-1970 and the Bicentennial issue. Total silver content is 0.1479oz with a weight of 11.5 grams, outer clad is .800/200 AgCu with a core of .209/791 for a final silver percentage of 40%. |

Bio O.K. Thanks. No matter really, as they are 40% silver. But I keep getting this info when I research the half. "outer layer composed of 80% copper and 20% nickel with a core of 20.9% silver and 79.1% copper. This yielded a net composition of 40% silver." Oh well !  Many opinions and authors out there I guess. |
